Charlottenburg (ʃaʁˈlɔtn̩bʊʁk) is a locality of Berlin within the borough of Charlottenburg-Wilmersdorf. Established as a town in 1705 and named after Sophia Charlotte of Hanover, Queen consort of Prussia, it is best known for Charlottenburg Palace, the largest surviving royal palace in Berlin, and the adjacent museums.
Charlottenburg was an independent city to the west of Berlin until 1920 when it was incorporated into "Groß-Berlin" (Greater Berlin) and transformed into a borough. In the course of Berlin's 2001 administrative reform it was merged with the former borough of Wilmersdorf becoming a part of a new borough called Charlottenburg-Wilmersdorf. Later, in 2004, the new borough's districts were rearranged, dividing the former borough of Charlottenburg into the localities of Charlottenburg proper, Westend and Charlottenburg-Nord.
Charlottenburg is located in Berlin's inner city, west of the Großer Tiergarten park. Its historic core, the former village green of Alt Lietzow, is situated on the southern shore of the Spree River running through the Berlin glacial valley. The Straße des 17. Juni road, former Charlottenburger Chaussee, which runs eastwards from Charlottenburg Gate through the Tiergarten park to Brandenburg Gate, connects Charlottenburg with the historic centre of Berlin-Mitte.
In the north and west, the Berlin Ringbahn and the Bundesautobahn 100 (Stadtring) mark the border with the Charlottenburg-Nord and Westend suburbs. Adjacent in the south is the territory of Wilmersdorf. Charlottenburg also borders on the district of Halensee in the southwest, as well as on Moabit, Hansaviertel and Tiergarten (all part of the Mitte borough) in the east and on Schöneberg in the southeast.
Archaeological findings in the area date back to the Neolithic era. Within the Margraviate of Brandenburg, on the land occupied by present-day Charlottenburg, there were three settlements in the late Middle Ages: the farmsteads Lietzow (pronounced leat-tsow) south of the Spree and Casow (pr.
